So i currently have a Samsung UN46D8000YF and i want to move it to my bedroom, and put something bigger in my (13'x16') Tv goes in a 10Ft wall and im about ~10'-12' away from it... and my budget is about $2k so the real question is... get a big 70" TV (like a Vizio 3d) or get a 55" Samsung 4K...

I have an xbox one and a ps4, so i game and watch netflix on it quite a bit.. my UN46D8000YF is perfect for that, but i want bigger!!!!

While i know xbox and ps4 dont support 4k yet, not sure if their hardware supports it.. i know netflix already stared releasing 4k content... Also im not sure if you can upscale any blueray movie and if it would look any better than 1080p

I would say if you're looking at M702i-B3 vs. a smaller 4K then definitely go with the M702i-B3.

If you're sitting 10+ft back you are going to be much happier with a 70" screen than a 55". I don't think right now is the time to jump into 4K personally. There are a lot of variables with the format that are yet to be pinned down both with hardware and software. I think you have an easy choice here especially with the 70" now having 36 local dimming zones.

Upscaled BD to 4K doesn't look any better. Only true 4k content looks phenomenal, so don't worry about the up scaling. Netflix only has House of cards , Breaking bad and smurfs 2 that I know of and you need a descent internet speed connection.

701 is last years model, while the 702 is this years model. The biggest difference between them is going to be the fact that the 701 is edge lit, and the 702 is back lit. The 702 should provide much better contrast judging from the other 2014 vizio models that implement the same setup.

702 has 36 different "zones" that can independently brightened or darkened, while edge lit TV's have their LED (usually) arranged as a strip of lights on the sides of the TV frame. You can really see the difference with scrolling white text credits on an all black background. An edge lit model will be lit up on the sides because the light has to travel all the way to the text..... If you have a back lit panel just the areas that have something displayed will be lit, providing better contrast.

Also vizio's website is down currently so wait for that to come back up, they may be posting their 4K models. They're supposed to be putting out a 55" 4K for $1,000. So you may be able to have your cake and eat it too soon with a 70" 4K potentially under $2,000.

How do 4k tv perform with a ps4/xbox one? Look better/worse than regular 1080p?

At those price points, something had to go. Given that the average person's 3D viewing has to be < 10%, they figured that full-array backlighting was a more important feature, as it affects picture quality 100% of the time.
